Please refer to Figures 9A and 9B. When the hidden engaging mechanism 1 is specifically used, the female threaded barrel 11 of the female engaging part 10 is spirally fitted inside a cabinet 30, so that the entire female engaging part 10 is located in the cabinet. Inside the body 30, the opening 123 of the female engaging body 12 will be provided on the surface of the cabinet 30. In addition, the male threaded barrel 21 of the male engaging piece 20 is spirally fitted into the inside of a plate body 31, so that the male threaded barrel 21 The second open hole 214 will be provided on the surface of the plate body 31, and the head 221 of the male engaging rod 22 and the neck 222 of the male engaging rod 22 will both protrude from the plate body 31. In this embodiment, , the cabinet 30 has a cabinet space 301 that can accommodate the panel 31, and the width of the cabinet space 301 is set to a cabinet width W1, then the width of the panel 31 is set to a width that is the same as the cabinet width W1. The same board width W2.

Please refer to FIG. 9C, FIG. 9D and FIG. 9E, which is a specific application of connecting the panel 31 to the cabinet 30. First, the panel 31 is placed inside the cabinet space 301 of the cabinet 30. Since the cabinet 30 is The width dimension W1 of the cabinet body is the same as the width W2 of the board body 31, so that the surface of the cabinet body 30 can contact the surface of the board body 31, and then the cabinet body 30 will be squeezed by the male engaging member 20. Rod 22, so that the male engaging rod 22 will move toward the inside of the male accommodating space 212 of the male thread barrel 21, and then the male engaging rod 22 will move to a retracted position P1, wherein, when the male engaging rod 22 is in the retracted position At position P1, the head 221, neck 222, body 223 and tail 224 of the male locking rod 22 are all located inside the male thread barrel 21. Next, the plate 31 continues to move along the surface of the cabinet 30 , so that the head 221 of the male engaging rod 22 can be aligned with the first groove space 124a of the coupling groove 124. When the head 221 is aligned with the first groove space 124a, the pushing spring of the male engaging member 20 25 will push the male engaging rod 22, so that the male engaging rod 22 can move from the retracted position P1 to an extended position P2, so that the head 221 of the male engaging member 20 can contact the guide surface 125 of the combining groove 124, Furthermore, the head 221 can be guided to the inside of the second groove space 124b of the coupling groove 124 through the guide surface 125. Therefore, when the head 221 is located inside the second groove space 124b, the neck 222 can be located in the card at the same time. The inside of the engaging notch 126a of the closing plate 126 allows the male engaging part 20 to be connected to the above-mentioned female engaging part 10, so that the hidden engaging mechanism 1 will not be exposed on the surface of the cabinet 30 or the surface of the board 31. Here, In the embodiment, when the male engaging rod 22 is in the extended position P2, the head 221 and the neck 222 of the male engaging rod 22 protrude outside the inside of the male thread barrel 21, and the body of the male engaging rod 22 223 and the tail 224 are located inside the male thread barrel 21 at the same time. In addition, because the outline of the engaging notch 126a is smaller than the outline of the head 221, the opposite sides of the engaging plate 126 can contact the head 221 and the body 223 respectively. Therefore, the head 221 cannot move out of the second groove space 124b through the engaging notch 126a.

Please refer to FIG. 10A and FIG. 10B for a specific application in which the plate body 31 is separated from the cabinet body 30. First, the plate body 31 moves upward inside the cabinet space 301 of the cabinet body 30, so that the head of the male engaging rod 22 The head 221 can move from the second groove space 124b of the coupling groove 124 to the first groove space 124a of the coupling groove 124, and then the head 221 will contact the guide surface 125 of the coupling groove 124. However, in When the plate body 31 continues to move upward, the male engaging rod 22 can move from the extended position P2 to the retracted position P1 through the head 221 touching the guide surface 125. Then when the male engaging rod 22 is located at the retracted position P1 , the head 221 will touch the surface of the cabinet 30, and then the board 31 can be separated from the cabinet 30.

The above-mentioned embodiments are only for the convenience of illustrating the invention and are not intended to limit the invention.
